Romelu Lukaku turned on his Manchester United teammates after their defeat last week at Chelsea.
Lukaku was fuming about the lack of service from his teammates upon his return to Chelsea, according to a dressing-room source.
The Belgian striker has endured a seven-match goal drought in the last month for United.
The Sun says Lukaku was said to be one of the most vocal in the post-match inquest among the squad minutes after the defeat.
He was making his first return to his old club since joining United in a £75million deal after it looked like he would be re-joining Chelsea from Everton.
Alvaro Morata popped up with Chelsea's winner to further heap pressure on Lukaku over comparisons with the Blues No9.
